Title: Wire driving gear
Inventor: NAKAZAWA FUMIKIYO
IPC: H02K23/68
Filed: 1988-08-18
Abstract: PURPOSE:To prevent water from infiltrating into an electrified section in a driving motor by setting a space between a recessed section internal-surface formed at the upper end section of a rotor shaft, and the lower end section of a wire guide. CONSTITUTION:When a rotor shaft 9 is rotated forward (or reversely) by a driving motor 1, then a wire 14 is directed upward (or downward) and is fed in the axial direction. Between the internal surface of the recessed section 13 of the upper end section of the rotor shaft 9 and the lower end section of a wire guide 15, a gap G is formed. Accordingly, when water infiltrates into the driving motor 1 through the wire 14 and the wire guide 15, the water is prevented from leaking outside the rotor shaft 9 due to the recessed section 13. The infiltrating water can be discharged outside the driving motor 1 through the hollow section 9a of the rotor shaft 9.

Title: Controlling system for four-wire space division type electronic exchange
Inventor: NISHIKIORI SHIYOUGO
IPC: H04Q3/545
Filed: 1981-12-21
Abstract: PURPOSE:To obtain easily a four-wire telephone exchange having a short duration, by remodeling a channel controller easily and partially without changing the control of a two-wire telephone exchange. CONSTITUTION:In case that a path is connected from an incoming repeating trunk TRKA to an outgoing repeating trunk TRKB, channel controllers SPC0 and SPC1 connect designated paths of networks NW0 and NW1 respectively on a basis of commands from a central controller CC. Next, controllers SPC0 and SPC1 transmit respective control operation advance information individually. Individually transmitted control operation advance information are allowed to pass through an AND gate circuit G; and when conditions of both controllers SPC0 and SPC1 become complete, information are transferred to the controller CC to report the completion of connection of the exchange. Then, paths 1 and 2 are connected to constitute a four-wire path. In this method, the four-wire telephone exchange is connected by transmission of the same commands as the two- wire telephone exchange from the controller CC.

Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To provide a wide heating power adjustment range by changing over from the state of fuel gas to be supplied to both pressure-equalizing compartments to the state of fuel gas to be supplied only to the upper pressure-equalizing compartment when the flow rate of supply gas is changed from high to low. SOLUTION: An upper pressure-equalizing compartment 36 is formed when a second burner head 33 is loaded on the upper part of a first burner head 32. A resistor 34 is provided in a central open hole 9 where the resistor 34 is provided with a round hole which regulates the amount of mixed air which flows into the upper pressure- equalizing compartment 36. In the when the amount of supply gas to a burner is reduced from a maximum to a minimum by operating a gas adjustable control 15, if the flow rate of gas to be supplied to a side pressure-equalizing compartment 35 reaches a specified flow rate, a turbulent mixed gas, which flows in a mixing pipe 4 turns into a laminar flow running only in the upper area and the mixed gas flows only into the upper pressure-equalizing compartment 36 and is prevented from flowing into the side equalizing compartment 35. Combustion flames of a first row of burner ports 38 are extinguished. This construction makes it possible to throttle the heating power of a burner having a larger capacity to a low flame capable of cooking food boiled and seasoned.

IPC: H01S5/00
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To enhance the intensity of photoluminescence drastically by adding erbium and nitrogen, as an emission center, to a single crystal of gallium phosphorus. SOLUTION: A GaAs substrate is prepared as a single crystal of gallium phosphorus and implanted with erbium ions at a dose of 1×10<13> cm<-2> with energy of 1MeV followed by implantation of nitrogen ions at a dose selected in the range of 1×10<13> -1×10<16> cm<-2> . Upon finishing the ion implantation, the GaP substrate is annealed in argon atmosphere for 10min at a temperature selected in the range of 600-1100 deg.C. The intensity of photoluminescence has a tendency to increase as the dose increases. When the dose is lower than 1×10<14> cm<-2> , it is difficult for erbium and nitrogen to become the emission center. The inventive semiconductor enhances the PL intensity by a factor of about 8 as compared with one provided with no nitrogen. In other words, the intensity of photoluminescence can be enhanced drastically.
